Figure 1

Morphology-controlled vdW heteroepitaxy of ZnO nanostructures on hBN substrates. Schematic of the fabrication process and tilt-view field-emission scanning electron microscopy images of (a and b) ZnO vertical nanoneedle arrays and (c and d) nanowall networks. ZnO nanoneedles and nanowall networks were obtained using pristine hBN and plasma-treated hBN substrates, respectively.
